How long will it take before I start seeing effects from anorexia/bulimia?

Besides the obvious low weight (I'm 5'7, 120 lbs now, not too low, but I've kept that weight even as I've grown in height) I really can't pinpoint any other negative effects my eating disorders have had on my body. I'm 15, male and if you took one glance at me you wouldn't be able to tell I was anorexic/bulimic. I've been doing this for two years now, and I never feel an acidy feeling in my throat, my teeth are healthy, I don't smell bad, I haven't broken any bones, and whatever other side effects ociated with these ED's, I don't have. Now, I'm not saying I'm immune to them, because I know if I keep going like this they'll eventually show up. However, how long will it take? How long can I keep this up? Am I slowly destroying my heart, my liver, or my kidneys? Keep in mind I've been doing this consistently for 2 years (daily). I'm trying to stop (I'm seeing a psychologist and my parents are really trying to help me) but it's incredibly hard. Thank you!
